Yes Sten-Arne, the place is indeed the "Great" wall of China.
And "pijiu" (in pinyin) or as you wrote " 啤酒 " in mandarin characters is 'beer' in Chinese. Being able to say something that sounds like "pee joo" is a useful bit of knowledge on the great wall.

Drinking a beer on another UNESCO World Heritage Site; in China. With the ghosts of Nixon, and every other western head of state in the last 50 years walking around me. Who'da thunk it?

(Btw this is the Mutianyu section of the great wall about 70 km's from Beijing.)
